REGULATIONS FOR CARRYING INTO EFFECT THE 
EXECUTIVE ORDER OF THE PRESIDENT ESTABLISH- 
ING DEFENSIVE SEA AREAS. 



Whereas, in accordance with section forty-four of the act entitled 
"An act to codify, revise, and amend the penal laws of the United 
States," approved March fourth, nineteen hundred and nine, as 
amended by "An act making appropriations for the naval service 
for the fiscal year ending June thirtieth, nineteen hundred and 
eighteen, and for other purposes," approved March fourth, nineteen 
hundred and seventeen, defensive sea areas have been established by 
my order of April 5, 1917. 

Now, therefore, I, Woodrow Wilson, President of the United 
States of America, do hereby authorize and promulgate the fol- 
lowing orders and regulations for the government of persons and 
vessels within the limits of defensive sea areas; which orders and 
regulations are necessary for purposes of national defense. 

I. In the neighborhood of each defensive sea area entrances have 
been designated for incoming and outgoing vessels, including, in 
the case of areas across which more than one channel exists, an en- 
trance for each channel. These entrances are described in Article 
X of these regulations in conjunction with the areas to which they 
respectively pertain. 

II. A vessel desiring to cross a defensive sea area shaU proceed 
to the vicinity of the entrance to the proper channel, flying her 
national colors, together with International Code number and pilot 
signal, and there await communication with the Harbor Entrance 
Patrol. It is expressly prohibited for any vessel to enter the limits 
of a defensive sea area otherwise than at a designated entrance 
and after authorization by the Harbor Entrance Patrol. 

III. Boats and other craft employed in the Harbor Entrance 
Patrol wiU be distinguished by the union jack., which will be shown 
from a position forward; they wiU also fly the usual naval pennant. 
At night they may show a vertical hoist of three lights — white, red, 
and white, in the order named. 

IV. On receiving permission from the Harbor Entrance Patrol to 
enter a defensive sea area, a vessel must comply with all instructions 
as to pilotage and other matters that she may receive from proper

authority, either before or during her passage across the area; it is 
understood that only upon condition of such comphance is the said 
permission granted. 

V. No permission will be granted to other than a public vessel 
of the United States to cross a defensive sea area between sunset 
and sunrise, nor during the prevalence of weather conditions that 
render navigation difficult or dangerous. A vessel arriving off a 
defensive sea area after sunset shall anchor or lie-to at a distance 
of at least a mile outside its limits until the following sunrise ; vessels 
discovered near the limits of the areas at night may be fired upon. 

VI. No vessel shall be permitted to proceed within the limits of a 
defensive sea area at a greater speed than five (5) knots per hour. 

VII. All matters pertaining to fishery and the passage of small 
crafts within a defensive sea area shall be regulated by the senior 
officer of the Harbor Entrance Patrol. 

VIII. These regulations are subject to modification oy the senior 
officer of the Harbor Entrance Patrol when the public interest may 
require ; and such notification as circumstances may permit will be 
issued regarding modifications thus made. 

IX. Any master of a vessel or other person within the vicinity of a 
defensive sea area who shall violate these regulations, or shall fail to 
obey an order to stop or heave to, or shall perform any act threat- 
ening the efficiency of mine or other defenses or the safety of navi- 
gation, or shall take any action inimical to the interests of the United 
States in its prosecution of war, may be detained therein by force 
of arms and renders himself liable to prosecution as provided for in
